Give the bear plenty of room, allowing it to continue its activities undisturbed. Every bear has a zone of danger or personal space -- that is, the distance within which a bear feels threatened. If it changes its natural behavior (feeding, foraging or movement) because of your presence, you are too close. If you stray within that comfort zone, a bear may react aggressively in the form of a bluff charge, bodily contact, or even an outright attack.
